    These are instructions on how to unlock your iPhone using SAM. This method will work with the iPhone 4S, iPhone 4, iPhone 3GS, and iPhone 3G on any jailbreakable firmware including 5.x.

    Step One
    Jailbreak your iPhone. You can find instructions on how to do that using the iClarified Jailbreak Wizard.

    Step Two
    Tap to launch Cydia from your SpringBoard.

    Step Three
    Press to select Manage from the tabs at the bottom of the screen.

    Step Four
    Press the large Sources button.

    Step Five
    Press the Edit button at the top right of the screen.

    Step Six
    Press the Add button that appears at the top left of the screen.

    Step Seven
    Enter and press the Add Source button.

    Step Eight
    Press the large Return to Cydia button.

    Step Nine
    Press to select Bingner from the list of Sources.

    Step Ten
    Choose SAM from the list of packages.

    Step Eleven
    Press the Install button at the top right of the screen.

    Step Twelve
    Press the Confirm button to begin installation.

    Step Thirteen
    Once installation has completed press the large Restart SpringBoard button.

    Step Fourteen
    Insert your new SIM card and tap to select SAMPrefs from your SpringBoard.

    Step Fifteen
    Tap Utilities

    Step Sixteen

    Press to select De-Activate iPhone. Your ActivationState under “More Information” should now be “Unactivated”. If you don’t have De-Activate iPhone you can use De-Activate iPhone (clear push).

    Step Seventeen
    With SAM enabled, tap Method and choose By Country and Carrier.

    Step Eighteen
    Tap Country and choose the country of your ORIGINAL SIM.

    Step Nineteen
    Tap Carrier and choose your ORIGINAL carrier that your iPhone is locked to.

    Step Twenty
    For some carriers operating more than one Carrier ID you may need to select SIM ID. If you are unable to activate in Step Twenty Four then you have selected the wrong one.

    Step Twenty One
    Tap More Information and copy the IMSI under SAM Details to the clipboard.

    Step Twenty Two
    Tap Spoof Real SIM to SAM

    Step Twenty Three
    Go back to the main SAM screen and paste the IMSI number in your clipboard.

    Step Twenty Four
    Connect your iPhone to the computer and let iTunes reactivate your phone.

    “Double click “Phone Number” parameter at the main device screen and make sure that the ICCID matches that of your SIM card.” If not you need to start over from Step Fourteen.”

    Step Twenty Five
    Unplug your iPhone from the computer and close iTunes.

    Step Twenty Six
    Reopen SAMPrefs from your SpringBoard and disable it using the Enabled switch.

    Step Twenty Seven
    Connect your iPhone to the computer and launch iTunes again.

    You should get an error saying that your phone cannot be activated. This is normal. Just close iTunes and open it again.

    Step Twenty Eight
    In a short time you should see signal bars. Congratulations!

    Step Twenty Nine
    You should now backup your iPhone unlock ticket in case this method is ever blocked. You can find instructions on how to backup the unlock ticket here.

    If push notifications stop after this process, you can restore then with the Clear Push utility in SAM, followed by connecting to iTunes.

    Your phone will work normally with your SIM card and that SIM card ONLY since we have tricked iTunes to think that ICCID is one of the intended carrier’s. The phone can be rebooted and connected to iTunes freely without losing the “unlock”, at least for now.

    A big thanks to Loktar_Sun and Laforet for their contributions!
